I am trying to decode an asf wrapped MPEG4 file using decraw but the images I keep getting are, well, I dont know how to describe it. The first several raster lines are fine, but then the image becomes garbled. Here I have posted a copy of the original asf video on my website, as well as a copy of one of the decoded images.
A bitmap conversion of the file (hexedited form the pnm)
The original pnm as it was decoded from the asf file
